Augmented Reality and 3D modelling By Stafford Joemat Supervised by Mr James Connan

Augmented Reality Definition: Combines real and virtual Is interactive in real time Is registered in 3D What is Augmented Reality? Augmented Reality Technology and Computer vision : Information about the surrounding real world of the user, to become interactive and digitally usable. Software approach to Augmented Reality: Consistent merging of real-world images from a camera and virtual 3D images.(Done in Real Time)

Computer Vision Principles and Application: Pattern recognition: Where information of a known pattern is extracted from images, mainly based on statistical approaches. Image processing: Is used to transform one image to a new image after some changes are made. e.g., edge extraction 3D modelling: Is the process of developing a mathematical, wireframe representation of any three-dimensional object.

Image registration: Transforming different sets of data into one coordinate system. Registration is necessary in order to be able to compare or integrate the data obtained from different measurements. Video tracking: Is the process of locating a moving object using a camera. Continuation:

Marker based Augmented Reality: Augmented reality markers: Are small printable shapes that interact Augmented reality software. Markers used with help of a digital camera allows Augmented Reality software, to create 3-D images overlaid on the real-world image seen on screen.

Goals: Successfully superimpose a 3D modelled object on a Augmented Reality Marker. Track an Augmented Reality Marker ‘s location, using Edge Detection Determine the distance and Angle of the Augmented Reality Marker to adjust 3D model perspective
